Lukasz Kukawski of Good Old Games has said DRM treats legitimate customers like criminals, and discourages customers.
"Treating a legitimate customer like a potential criminal won't convince them to buy original copies of games," Kukawski told Adventure Classic Gaming.
"In our opinion a better way to get people to spend their hard earned money on original games rather than pirating them is to give them a good value for money - offer good games for reasonable prices, making the whole experience hassle-free, adding exclusive free goodies which they won't get with a torrent download.
"We believe adding those incentives are well worth all the work and effort rather than just adding a draconian DRM software which will only make legitimate customers' life more difficult."
Kukawski pointed out that pirated copies of games have the DRM stripped from them, meaning only legitimate customers ever experience its effects.
"Let's take EA's Spore which allowed you a limited number of installations or UbiSoft's Assassin's Creed 2 which forced you to stay on-line for the whole time you play the game," he said.
"Gamers were truly pissed that they are paying $50 for a game they can't play as they'd like to. I'm sure those DRMs actually pulled lots of people from buying the game or made them get a pirated version."
